Abstract

Methods for producing all natural non-toxic sublingual delivery systems that have improved absorption and onset profiles for active compounds, along with improved bioavailability and pharmacokinetics compared to tablets for oral administration.

Claims

exact text as granted — not AI-modified
1 . A method for producing a quick-dissolve sublingual tablet, comprising:
 formulating a mixture comprising a flavoring agent, sodium bicarbonate, citric acid, and a pharmaceutically active component in powder form; and   compressing the mixture to form sublingual tablets that dissolve in less than 30 seconds upon sublingual administration.   
     
     
         2 . The method of  claim 1 , wherein the sublingual tablets are round convex or round concave tablets. 
     
     
         3 . The method of  claim 1 , wherein the sublingual tablet has a concavity that enables pooled saliva to speed dissolution upon sublingual administration. 
     
     
         4 . The method of  claim 1 , wherein the sublingual tablets further comprise magnesium stearate, and microcrystalline cellulose. 
     
     
         5 . The method of  claim 1 , wherein the sublingual tablets further comprise croscarmellose. 
     
     
         6 . The method of  claim 1 , wherein the sublingual tablets further comprise microcrystalline cellulose. 
     
     
         7 . The method of  claim 1 , wherein the sublingual tablets further comprise sucralose. 
     
     
         8 . The method of  claim 1 , wherein the pharmaceutically active component comprises sildenafil or a sildenafil-analogue. 
     
     
         9 . The method of  claim 1 , wherein the pharmaceutically active component comprises sildenafil citrate. 
     
     
         10 . The method of  claim 1 , wherein the pharmaceutically active component is a statin. 
     
     
         11 . The method of  claim 1 , wherein the sublingual tablets further comprise a vegetable oil. 
     
     
         12 . The method of  claim 1 , wherein the sublingual tablets are formulated for rapid onset of action beginning within 5 minutes of sublingual administration. 
     
     
         13 . The method of  claim 1 , wherein the compression methods provide for controlled release of the pharmaceutically active component. 
     
     
         14 . The method of  claim 1 , wherein the sublingual tablets are formulated for rapid onset of action beginning within 5 minutes of sublingual administration, and peaking between 15 and 30 minutes after administration.
